摘要： An electrode probe is brought into contact with a measurement part on an outer surface of at least one of the positive electrode and the negative electrode of a sheet type cell, and quantity of electricity is measured at the measurement part, so as to evaluate the sheet type cell. The electrode probe may be connected to a voltage meter and to a charge source or a discharge source, and the evaluation made by detecting a charge characteristic that changes the cell from a non-charged state to a fully charged state, a discharge characteristic that changes the cell from a fully charged state to the non-charged state, or a measurement voltage of the voltage meter when the cell is in the fully charged state.

摘要： Systems and methods for calibrating a conducted electrical weapon (“CEW”) to provide a predetermined amount of current for each pulse of the stimulus signal. Providing the predetermined amount of current, close thereto, increases the effectiveness of the stimulus signal in impeding locomotion of a human or animal target. The calibration process enables a CEW to calibrate the amount of charge in a pulse of the stimulus signal in the environmental conditions where the tester operates and also in the field where the environmental conditions may be different from the environmental conditions during calibration.

摘要： A secondary battery status estimation device includes a sensor unit configured to detect a terminal voltage of a secondary battery, and an internal resistance calculator configured to calculate a direct current internal resistance of the secondary battery based on the terminal voltage and the charge-discharge current detected by the sensor unit. The internal resistance calculator calculates a direct current internal resistance based on the terminal voltage and the charge-discharge current detected by the sensor unit, in a stable period that is before starting a driving source for driving a vehicle and in which the terminal voltage and the charge-discharge current of the secondary battery fall within a predetermined fluctuation range, and in a high-current output period in which electric power for starting the driving source is output from the secondary battery and the terminal voltage of the secondary battery is brought to substantially minimum.

The method includes the following consecutive steps: supplying the cell with anode and cathode streams; abrupt and controlled variation of at least one of the following parameters: the pressure of the anode stream in the anode channel, the pressure of the cathode stream in the cathode channel, the flow rate of the anode stream into the anode channel, the flow rate of the cathode stream into the cathode channel, and the strength of the current exchanged between the two sides of the membrane; measurement of a first reducing fluid concentration in a first stream, including the cathode stream leaving the cathode channel; and deducing the presence or absence of leakage on the basis of the variation in the first measured concentration of reducing fluid over time. A corresponding fuel cell system is also provided.
